I just bought a Kobo Aura One, and so far am impressed. But a small c-shaped cluster of pixels is inverted -- it's black when it should be white, and white when it should be black. Of course, it's very tiny on this high-resolution screen, but it's still noticeable and bothersome to me. The c-shape of the cluster is only discernable when looking at the screen with a jeweler's loupe.

I haven't installed the inverse-video night-mode hack or anything else; this is fresh-out-of-the-box.

I've never seen anything like it on a Kobo E Ink device, and I've owned most models. On LCD displays, of course, you can get a stuck pixel that always remains one color -- but that's not what's happening here. And previous models of Kobo had the bright-pinprick-of-light problem that many have experienced, caused, perhaps, by dust or another defect in the screen coating. But this cluster isn't brighter or darker than any other pixels.

I can reliably observe these pixels doing the opposite of what all their neighbors are doing by going to menu Help | Getting Started, and paging back and forth between pages 8 and 9. The inverted pixels show as a white spot in the black circle on page eight, and a black freckle on the middle finger of the right hand on page 9. (The effect shows up all the time, regardless of what's on screen; the problem is NOT a defect in the images being displayed on those particular screens.)

Again, these pixels are not stuck; they're responding to input somehow, but doing the opposite of what they're supposed to do. Anyone seen anything like this before? Anyone know of a way to get rebel pixels to stop misbehaving? I've got screen refresh set to every page, and have tried numerous page changes in hopes that the bounce to inverse video at each page change would help, but it hasn't.

Many thanks!
